Cell phones have become increasingly popular in china these days. wherever you go you can see people using cell phones. many college students, even high school students, have cell phones.
Cell phones have brought people a lot of benefits, but the most important is that they are convenient. with cell phones in their hands, they can keep in touch with anybody they want. if they want to get some information from the internet, they can easily have their dream realized via cell phones too. furthermore, if someone has a heart attack or a traffic accident, a call to emergency hospital or to the police can quickly bring him the help he wants.
However, cell phones can also bring people problems. the most serious is the electric wave radiation which is thought to be harmful to users brains. another problem is that when people are having a meeting or having a class or at a concert etc, the ring of the cell phone may interrupt others. so i think people should use cellphones as little as possible and turn them off when they are attending important meetings or attending classes.
Addiction to Smartphones
Do you check your smartphone frequently? Do you feel distracted if your smartphone is not with you? When there’s no wifi or signal for your smartphone, will you get irritated? If you say yes, then you’ve got addiction to smartphones. Smartphone addiction is a phenomenon that causes a lot of troubles to people.
In the first place, it may cause some problems to your health, such as visual fatigue, cervical spondylosis, and even neurasthenia. A friend of mine suffers from a serious spine collapse due to her addiction to smartphones during pregnancy.
Secondly, if you keep playing with your phone when you are with your friends or family, you will spend less time talking to them. In fact, it is they who need and deserve to be cared for.
Lastly, an excessive reliance on smartphones may weaken your interpersonal skills. When you cannot find a place, you consult your GPS instead of consulting local people. You spare more time playing mobile games than playing real games with real people. As time passes, it’s possible that you may have difficulty in communicating with people.
Therefore, isn’t it better to get rid of smartphone addiction?
